Y., A cOR- IEORATION OF NEW YORK FLOOR FITTING Application filed March 27, 1930, Serial No. 439,416. Renewed September 15, 1932.

This invention relates to floor fittings for heat exchange systems of buildings and has sections together, but also to provide a sleeve member which serves both as a location means and as a liner for the opening through the floor. Our improved fioor fitting which essentially constitutes a sleeve, anchor and joint fitting serves to provide a support, sleeve and anchor for the riser pipe and to materially simplify and reduce the labor cost in the installation of the heating system. Other advantages of our invention are hereinafter set forth.

Heretofore it has been customary to project a riser pipe through registered openings in the different floor levels and to apply to such pipe at certain fioor levels only a supporting collar, each collar being adapted to rest on the top surface of a fioor'and serving to support the riser pipe, but these collars do not readily lend themselves to the convenient assembly of the riser pipe sections in their superimposedrelation, besides failing to provide as effective a seal between the abutting ends of the riser pipe sections which were anchored therein as is desirable in steam Our investigations have led to the discovery that these various objections can be efiectively overcome by the improved construction hereinafter described.

In the accompanying drawing forming a part of this specification Figure 1 is a fragmentary vertical section, partially in elevation of a building equipped with a heating installation embodying one form of our invention;

Fig. 2 is a fragmentary elevation, partially in vertical section, showing our improved anchorage flange and pipe fitting, isolated.

Referring to the drawing and the description shown therein, a riser section 7 is provided with a bottom terminal flange 10 which isadapted to co-operate with a similar flange 10' of an inverted riser section 7 that projects upwardly through the con crete flooring of a building and upon which the same is superimposed. A sleeve member 11 which, as previously stated, serves as a mold during the pouring of the concrete floor to form the aperture for the reception of the riser section, is provided with a bottom flange 12 and vertical ribs 13, said sleeve belng-of an inverted truncated cone configuration at its upper end as indicated by the reference numeral 14. Two apertured plates 15 and 16 respectively, which preferably are of generally triangular shape and each of which has a series of bolt-receiving aper tures 17, 17 "that are adapted to register with each other and to admit of the reception therethrough of bolts 18, serve to secure the opposing flanges 1O, 10 of the pipe sections 7 and 7 together, this being accomplished by applying the nuts 19 to the upperend of the bolts and screwing the same home until the flanges 10, 10 are in intimate contact and the upper ends of lugs 20, which constitute flattened heads of said bolts, are in engagement with the lower face of the plate 16. 'lhereupon cap screws 21 mounted in the lugs are turned down until the same engage and ride downwardly on the inclined face of the conical end 14 of the sleeve 11, which latter has been previously anchored in the concrete floor, and thereby the said pipe sections will be held in hermetically tight engagement with each other and anchored to the sleeve 11. a

As shown, the plate members 15 and 16 are preferably of triangular shape and the so-calledcentral aperture thereof is some What Offcenter, whereby riser-"sections are permitted to hug quite closely the outer wall of the building, but obviously, if desired, circular discs or plates of other shapes could be employed and the central apertures there through likewise disposed somewhat off center.

In order to guide or aline the lugs 20 so that they will present the cap screws carried thereby with their longitudinal axis substantially at right angles to the axis of the riser pipe section which it is desired that the lugs shall engage, we provide stop pins or lugsa, the same being formed integrally on 5 properly alined position.

Among the various advantages possessed by our improved construction are its simplicity and cheapness, as well as the fact that our improved device forms a permanent and hermetically tight joint.

While we have described and illustrated certain preferred embodiments of our invention in the specification and drawing of this application, we do not wish to be understood as limiting our invention thereby as various changes therefrom may be made without departing from the spirit of the invention as embraced within the scope of the appended claims.

Having thus described our invention, What we claim and desire to obtain by United States Letters Patent is V 1.
